To all whom it may concern:

Be it known that I, HERBERT S. HUM- PHREY, a citizen of the UnitedStates, and

on line 6-6 of Fi resident of Kalamazoo, in the county of Kalamazoo andState of Michigan, have invented certain new and useful Improvements inInstantaneous-Water-Heater Casings, of which the following is aspecification.

The primary object of this invention is to provide a sectional body orshell for instantaneous water heaters, the parts of which may be readilyassembled and as conveniently taken apart. Provision is had for soarranging the separable parts of the body and for so supporting thewater circulating coil therein that the latter may be removed withouttaking down the entire body. The upright portion of the body wall isembodied in a post and panel construction, in the preferred adaptationthe panels removably fitting and secured to the posts, the latter risingfrom a suitable base and at their upper ends sustaining a top or crownto which a flue is connected in the usual manner. Also embodied in thesectional formation is a horizontal belt-like ring which is supported bythe posts and separates the upper and lower wall panels, and alsoprovides a support for the circulation coil as well as a thermostatictube if the latter is used.

In the accompanying drawings, is a front elevation of body, portionsthereof being shown in section. Fig. 2 is a view of the heater bodypartly in elevation taken at right angles to Fig. 1, and partly insection on line 2-2 the improved heater of Fig. 5. Fig. 3 is a view ofthe heater body shown partlyin top plan and partly in sectional plan,the portion in section being taken on line 33 of Fig. 1.. Fig. 4 is asectional plan on line 4-4 of Fig. 1, and Fig. 5 is a similar View takenon line 55 of Fig. 2. Fig. 6 is a vertical longitudinal section throughone of the upright posts taken g. 3. Fig. 7 illustrates in detail one ofthe wall-forming panels.

Referring to the drawings, 2 designates a base of any suitableconstruction, in the present adaptation being of circular form andsupported by legs 8. Also as here shown, the base supports the coilheating burners 4 to which gas may be supplied Specification of LettersPatent.

through ducts 5 in the bottom of the base, all as heretofore practicedand for which no novelty is claimed.

The top edge of the base constitutes the upstanding annular rim orlip,and at the outer side thereof is the annular flange or shoulder 7.Rising from base 2 are posts 8 having their lower angular extremities 8countersunk at 9 in enlargements of flange 7, being secured thereto byscrews 10. The upper extremity of each post is similar to its lowerextremity, being of angular formation as indicated at 8" and countersunkat 9 in the lower portion of the annular crown or top 12 and secured byscrew 10. The lower edge of the crown forms the annular depending rim13, above which is the external annular shoulder or flange 11 which,respectively, are complementary in form with rim 6 and flange 7 of thebase. The posts comprise a substantial support for the crown, and thebase, posts and crown constitute a panel supporting skeleton which maybe readily assembled and as conveniently taken apart.

The central outer portion of each post is of bead-like form, asindicated at 15. The inner portion of each post is of forked formation,the longitudinal ribs or wings .16 thereof diverging from bead 15,thereby forming an upright channel 17. Bridging this channel at suitableelevation above base 2 is lug 18.

19 is a belt-like ring which is formed with the outer peripheral flange20', and at opposite sides of this flange are, respectively, theupstanding and dependingannular rims 21 and 22. Flange 20 is notched at2 to cmbrace each of posts 8, with tongue-like projections 24 within thenotches and adapted to fit the post channels 17 and rest on lugs 18,thereby supporting the ring 19 in interlocking engagement with theposts, bracing the latter and materially strengthening the structure.The ring may be moved vcrtically between the posts and tilted andmanipulated as may be necessary to either place it in position or removeit. In addition to its frame bracing functhm, ring 19 separates theupper and lower panel spaces and door openings, and also serves as asupport for the lower extremity c of the circulation coil C, beingformed with the open-top seat 25 to receive the same. And if athermostatic tube T is employed beneath the coil, as shown in patent toEdwin Ruud, No. 682,345,-September 10, 1901, opposite sides of the ringmay be formed .with similar seats 26. It will be understood, however,that the invention is not limited in this regard, nor to the specificmeans here shown to flange 7 of base 2. The free edge forlbracing theposts and for supporting the 001 The wall-forming panels located abovering 19, and panels 31 beneath the latter, are of like construction, inthe present adaptation, each panel being of segment form and consistingof the separated outer and inner sheet-metal plates 32 and 33,respectively, with their edges seamed together as indicated at 34. Thepanels fit the spaces between adjacent posts with their lip-likevertical edges secured to. post flanges 16 by screws 16. The upperpanels enter between outstanding flanges 14 and 20, respectively, ofcrown 12 and ring 19, with the lip-like upper and lower edges of thepanels fitting the rim formations 13 and 21, respectively of said parts.Similarly, the lower panels 31 are fitted between and secured toadjacent posts and between the base flange 7 and ring flange 20 and attheir upper and lower edges engage, respectively, rim 22 of ring 19 andrim 6 of base 2. The upper panels are of like size and can be locatedinterchangeably in the panel spaces, and the same would be true of thelower panels but for the notches necessary to embrace the lower coilextremity 0' and the thermostatic pipe T.

One of the upper panels constitutes a door 35 for the coil-inclosingportion of the heater body, being hinged at 36 to flange 14 of crown 12,and at its lower end similarly hinged at 36' to ring flange 20. Acorresponding lower panel provides a door 37 for the burner-inclosingportion of the body, being hinged'at 38 to ring flange 20 and at 38' ofeach door is provided with a latch 39. One or more of the lower'panelsmay have its inner and outer plates perforated at 40 and 40,respectively, for admitting air to the burner chamber.

When it is necessary to renew or repair the circulation coil, it may belifted out of the heater body upon removing crown 12, and the upperpanel which overhangs the lower coil terminal 0', and thermostatic tubeT may be similarly removed upon taking off the panels which confine itin seats 26. Thus it will be seen that the circulation parts are readilyaccessible, and their complete removal may be accomplished by takingapart only a small portion of the-body or shell. The air insulatedwall-forming panels minimize heat radiation, thereby increasing theelliciency of the apparatus and decreasing the temperature of the roomor compartment in which the heater is located. And this is of specialimportance as the present invention is designed especially for heatersof relatively small size for individual apartment use.

The post and panel construction provides a readily separable orknockdown heater body or shell of maximum strength and minimum weight.While a body of circular form is preferred, the invention is not limitedthereto.
